Lone Wolf and Cub for father and son.
uchuu kyoudai and full metal alchemist for Brothers
I know there are tags for this but many of them dont have father-son and brothers as the main characters of the manga. i want both of them to be the main characters. also want to read you opinion aswell.
some seinen action adventure would be nice and please no shounen ai or yaoi. i find a lot of them in the search engine for father-son and brothers.
